MMS is for those trying to kill off some type of infection when nothing else will work. I think it really isn't necessary to take the large doses. I wouldn't take much more than 5 drops at once.
You could be experiencing some type of die off or detox or you might have oxidized some tissue in your body that you shouldn't have. Who knows?
If you're healthy I would experiment with other things like Colloidal Silver or Lugols Iodine. Super food D3 etc.
